Bullhead Lake

On the LakeGrade scale Bullhead Lake grades a B, with clarity at 12.9 ft and phosphorus readings still being added placing it above the Minnesota median. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. The lake bottoms out at 34 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. With 1,067 acres of surface and 24.1 miles of shoreline, Bullhead Lake is a large water by Minnesota standards — recreational pressure is spread across a long shoreline. Bullhead Lake sits at rank 55 of 93 in Becker County, in the lower half of the local distribution.
